Researchers have developed SpecSlot, a novel pixel-space generative Transformer designed to improve efficiency and detail in image generation. This model decouples output detail from the length of the global attention sequence by expanding spatial anchors into multiple slots, each handling different frequency bands of DCT coefficients. Only the lowest-frequency slots engage in global attention, while all slots interact locally, allowing for increased spectral detail without a proportional increase in computational cost. SpecSlot has demonstrated competitive or superior performance compared to existing models like JiT on benchmarks such as ImageNet and DPG-Bench, achieving better Fréchet inception distance with fewer FLOPs.
